The present invention relates to materialunrolling attachment fornap-raising machines and has for an object to provide a deviceconstructed and arranged for incorporation in a nap-raising machine forknit goods or other nap-containing fabrics which: will act to; stretchandsmooth the material preparatory to the delivery of the ma-v terial tothe feed rolls andfito. the nap-raising .In nap-raising,.machines, aspresentlycon structed and used two attendants are required, one to eachside of the, machine constantly engaged in unrolling the knittedmaterialqasit isbeing fed-into the machine. Sweaters'and: other 7-1 knitgoods are ordinarily-originally fabricated in; a several bodyandsleevelengths knit inv one con tinuous piece to form. a stripe.

The

' feed rollers l4 andlS pull the material'longitudinally into thenapping machine over the tables and between the belts-andpre'ssureplates. Before starting theoperation the carriages are adjusted byenergizing the motor 3| so that the belts H and I! may be moved tocorrect position towards or away from one another to accommodate thewidth of the stripe about to be fed. When this adjustment has beeneffected the limit switches 32 and 33 ale-energize the motor 3| eitherat the narrowest or widest limits permissible by the width of machine.

The main motor 46 is thenenergized to drive the belts and feed rollersas well as the napping brush and the stripe will thereupon movelongitudinally into the machine and at the same time be subjected totransverse stretching movements of the belts IT and H which. cooperatingwith their pressure plates will unroll the side edge Y portions of thestripe and stretch and smooth the stripe so as to place it in mostfavorable conhundred per cent of the napping of the trans- I versedimension chine.

The rock frames 51 pivotally carrying the pressure plates may be limitedin the downward movements of the pressure plates by complemental stopsill, H. The springs 63 are in effect an adjustable counter balance forthe weight of the plates carried by the rock frames 51. The platesimpose their weights upon the material both by a vertical slidingmovement in the rock frames 51 and also by the angular movement of therock frames 51 about the pivots 58.

Although I have disclosed herein the best form of the invention known tome at this time, I reserve the right to all such modifications andchanges as may come withinthe scope of the following claims.
